WINDOW-VENTILATOR.

To all whom'it may concern:

'Be it known that I', GEORGE W. KENNEDY,

citizen of the AUnited States, residing rat Delaware City, in the county of Newcastle and State of Delaware, have invented certain newand useful Improvements in Window- Ventilators, of whlch the following is a specification. Y

The present invention relates to certain new and useful improvements in window ventilators, the ob]ectbeing to rovide a simple device of this character em odying a novel construction whereby an air. deflecting slat can be adjustably mounted between a air of oppositely disposed end plates and eld at fixed angles as may be required by various conditions. l

A further object of the invention is to so design the window ventilator that it can be readily applied to any of theconventional types of window frames without in any manner defacing or altering the same.

For a full description of the invention and the merits thereof .and also to acquire a knowledge of the details of constructlon and the meansfor eecting the result, reference is to be had to the following description land accompanying drawings, in which:

Figure l is a perspective view of a portion of a window frame having the ventilator applied thereto. Fig. 2 is a vertical sec- .t1onal viewl through the same. Fig. 3 is a similar view showingl the Ventilating slats as folded against eac other and forming a vertical barrier. Fig. 4 is also a similar view showing the Ventilating slats in inoperative position. Fig. 5 is a horizontal sectional view though the window frame. Fig. 6 is a window frame and shows a modified form of end late. Fig-.7 is a detail view of the modified orm of end plate shown in Fig. 6. 8 is la perspective view showing a modified construction of the deflecting slats. 9 is a plan view of a further modification of the end plates. Fig. 10 is a perspective view of an embodiment of the inventlon wherein the deflecting strips are provided with retractable tongues. Fig. 11 is a detail view of a modification.

Corresponding and like parts are referred to in the followin description and indicated in all the views o the drawings by the same reference characters.

In its broadest phase the invention comprises essentially an air deflecting slat ex- Speecation of Letters Patent. Application filed March 29| 1907. Serial No. 365.350.

Patentedy Maren a', 190s;

frame, and sideplates carried byl opposite sides 4of the window.. frame, the said an' deflecting slat and side plates having av tongue:

and socket connection whereby the slat can be .held in any one of a-series of positions as' may be found desirable.

In theform of the invention shown in 1 the air deiiecting slat 1- is shown as pro tending' transversely i across the ,window s i vided at its opposite ends with the longitudinally disposed lugs 2 which are located adjacent one of the longitudinal edges thereof and are designed to engage any one of a s'ey ries of sockets or notches formed in the end plates 3 andsecured to the window jambs on opposite'sides of the frame. construction ofthe end plates 3 it will be observed that the same are formed with: a pair of vertically disposed sockets or notches 4 and 5 extendin downwardl from the upper edge thereo and-the soc et 5 being deeper than the socket 4 and located nearer to the rear edge of the plate. Below the socket 5 and inclining downwardly from the rear edge of the plate is an intermediate socket '6, and toward the lower portion of the plate is a horizontally disposed socket 7 having an inclined socket 8 in communication therewith. As shown in Fig. 1 it'will also be observed that a second air deflecting Slat 9 maybe employed which has one of its longitudinal edges hinged or loosely connected to In the specific a corresponding edge of the slat 1 in any' suitable manner so as to fall against the same and have a s 'ng motion with relation thereto. It will lie noted that the lugs 2 have an angular formation and that the sockets correspond in shape to the same,- thereby enabling an interlocking connection to be produced between the said tongues and sockets for locking the deflecting slat 1 in an adjusted position and preventin anyswinging movement of the same. Wlien the lugs 2 are ositioned within the sockets 4v of the side p ates 3 1n such a manner that the air deilecting slat 1 extends verticali upwards, the Slat 9 is pendent from the ower ed e thereof and is inclined forwardly at an ang c so as to deflect u wardly an air which might enter were the lbwer win ow sash slightly elevated. HoweverA should the air deflecting slat 1 extend downwardly when the 'lu s 2 are received by the sockets 4, the slat 9 will fall against the slat 1 to produce a vertical barrier against direct currents of air as indicated inFig. 3. v When thelugs 2 vare engaged by the sockets 5 the deiiecting slats areY held in a position similar to that described, the essential difference residing in the fact that the p endent slat 9, the lower edge of which vrests upon the window sill, is disposed at a greater angle from the vertical. Should the lugs 2 be placed within the intermediate inclined socket 6 both of the air deiiecting slats 1 and 9 will be inclined, a similar condition will exist when the lugs 2 engage the lower inclined sockets 8, except that in the latter instance the two plates will beinclined at a greater angle to the vertical and will not oder as effective a barrier to a direct current of air entering through the window.' When the slats are not in position they can be folded against each other so as to rest upon the window sill as shown in Fig. 4, the lugs or tongues 2 being received by the horizontal sockets 7.

' The air formed of any suitable material and may either comprise a pair of wooden strips, or a pair of metallic strips yhaving their adjacent longitudinaly edges loosely connected so as to have a swinging movement with respect to each other. Under some conditions it may be found desirable to cut away or bevel the lower edge of the pendent air deflecting slat 9 as indicated at 10,

In Fig. 8 a slight modification is shown in which the pendent air deilecting slat 9a is shown as formed of sheet metal and is provided at its lower edge with a laterally extended iange 11 designed to lit over the window sill in order-to prevent any air from finding its way under the air delecting slat. Any

. suitable mechanical means may be employed for providing the ton of the air deliecting s at 1, and in the present instance the said tongues are shown as formed in connection with plates 12 which are secured to the said slat 1.

The side plates 3 are preferably secured along their outer edges to strips13 extending along the portion of the window j amb adj acent the sash, and with this construction the notched or socket portions of the plates are held in a spaced position from thel .window j amb, thereby affording a clearance space for the operation of the tongues 2 which effectively prevents any binding of the latter. However should the window frame not be provided with the strips 13 a modification may be employed similar to that shown in Fig. 9 in which the end plate 3 has the rear edge thereof secured directly to the window jamb and is provided with an offset portion 14 which throws the body portion of the end plate away from the window jamb and provides the desired clearance space. Should the sill of the window frame not be oit' a sufficient depth to form a support for the 'deiiect ing slats when folded together and held in an inoperative position with the tongues 2 in deiiecting slats 9 and 1 may be" the side plates, a tongue an es 2 at opposite ends j the horizontal sockets 7, the lower edge of the plates 3 may be formed with the inwardly extending ledges 15 designed to serve as a support for the said air deiecting slats.

A still further modication is shown in Fi 10 in which the end plates 3b are formed wit a series of sockets lwhich are in the nature of openings `formed in the said plates. ln this instance the tongue 2-b mounted upon the air deecting slat 1b is retractable and is provided with a iin er-piece 17 by means of which it can be rea ily withdrawn from any one of the openings or sockets 16. It is also within the province of the invention to form the endplates with tongues and to provide the air deilecting slat with sockets engaging the tongue. In Fig. 11 the end plates 3c are formed along their rear edge portion with a series of tongues 18 dis osed at diderent angles and positions wit relation to each other, and the air deflecting Slat 1 carries socket ieces 19 at opposite ends thereot1 designed) to engage with a selected air of the .tongues 18 to hold the air deflecting slat atthe required an le.

Having thus escribed the invention, what is claimed as new is:

1. In a window ventilator, the combination of oppositely disposed side plates, an air delecting slat adjustably su ported between d socket connection being provided between the side plates and deflecting slat and the said tongues and sockets being of angular formation and adapted to interlock with each other to hold the deflecting slat in an adjusted position,

and a second air deiiecting slat hinged to one A.

of the longitudinal edges of the first 'mentioned air delecting slat and designed to be folded against the same in either a vertical or horizontal position or to hang at an angle to the same.

2. In a window ventilator, the combination of oppositely disposed side plates rovided with a series of corresponding soc ets of angular formation, and a pair of air delecting slats having the longitudinal edges thereof hinged, one of said slats having angular tongues projecting from the opposite ends thereof adjacent the edge to which the opposite slat is hinged, the said tongues bein adapted to interlock with a selected pair o the corresponding sockets in the side plates to hold the deflecting slats in an adjusted position.

3. In a window ventilator, the. combination of a air of side plates each of which `is provided 1n its upper ed e with a pair of vertical sockets one of whic is deeper than the other, and also at its rear edge with an inclined socket and a horizontal socket, an air deecting slat provided at its extremities with angular tongues designed to interlock with a selected pair of the sockets to hold the air deiiecting slat in an adjusted position, and

a second air dcl'lectinv slat hinged to the first mentioned slat and designed to hang therel'roni atan angle varying according to the sockets engaged by the tongues of the irst mentioned slat.

4. ln a window Ventilator, the conibination oll oppositely disposed side plates, an air delleeting slat adjustably supported between the side plates, and a second air delccting slat hinged to one of the longitudinal edges ol` the first mentioned slat, the second nientioned slat being provided at its free edge with ai laterally extended ilange for the purpose specilied.

5. ln a window Ventilator, thc combination ol'v oppositely disposed side plates provided with a plurality of corresponding.

sockets of angular orrlnation, an air deliecting slat inounted between the side plates, and retractable tongues carried by opposite ends of the deflecting slat, the said retractable tongues being of angular formation and ada )ted to interlock with any selected pair of tlie before mentioned sockets to hold the dcllecting slat in an adjusted position. y

In testimony whereof I alix my signature in presence of two witnesses.
